After graduation, I entered Hong Kong Technical College
(HKTC) and studied Building Construction. I stayed there until December
1964. While in the last year at HKTC, I played for the college soccer
team as the left half back and won the championship of the Post
Secondary School League.

After leaving HKTC, I worked as an Engineering Assistant
in the Hong Kong Public Works Department, Traffic Engineering Division
until mid-July 1968. These three and half years were the most enjoyable
of my working life so far. I went through several sections such as:
street lighting, transportation planning, highway geometric (or
functional) design, and traffic light signal system design. I was really
lucky at the time, every time I moved into a section, I reported
directly to the section engineer. Under normal circumstance, an
engineering assistant reported to an assistant engineer and then in turn
to the engineer. There were only three fully trained traffic engineers
at the time in Hong Kong. One was the Chief Engineer, the other two were
Senior Engineers. With my technical background and surveying training
back in the technical college, I managed to pick up the required
expertise really fast. For those class mates back in Hong Kong, you can
still see two pieces of my geometric design work. One is the Cotton Tree
Drive and the other is the flyover at the intersection of Garden Road,
McDonnell Road, and Robinson Road.

While working full time, I also gave private tuitions
and studied for the GCE examinations. By sheer luck, I finally passed
the GCE O-Level English on the fourth attempt. Because of my
achievements at work, almost all the engineers in the Traffic
Engineering Division advised me leave Hong Kong and further my study.
